Hey all, new to the forums, I did a search and didn't find anything that quite answered my questions so I hope this isn't a repeat! After years of staunch Windows support I'm finally making the switch. I'm sick of sub-par 3rd party hardware failing after two years. The MBA seems pretty perfect for me, but I recognize that I'm basically buying a four year old machine and I'm wondering where people would recommend I upgrade (if at all). I will be using this for light work stuff, music, video, web browsing -- very basic. Is it worth upgrading the RAM to 8GB or the processor to an Intel i7? Anyone know if either of these is a significant performance chokepoint for home computing? I'm looking to spend less than $1500. I would also consider the MBP if there's a compelling case, but because of consistent durability problems I'm leaning towards Solid State. Any thoughts on this? Thanks for your help!
